I have a casio exilim Z77 camera. It fell in the sand at the beach and ever scince is giving a blurred view. i gave it to the casio dealors here but they say some part of the camera has been damaged and they cant get that part. And now i have to change the entire lens which is almost equal to the cost of a new camera.
